Project Task Version History: Track Every Change With Full Before/After Diff
See every change to every task, who changed it, when, and what it looked like before. Deadline moved, assignee swapped, status changed, full audit trail per task.
The 'who changed this?' moment
Every PM has experienced it: a task's deadline has moved, or an assignee has changed, and nobody knows who did it or when. The Slack message asking 'did anyone touch Task X?' produces three 'not me' responses and no answer. This is not a communication problem. It is an audit trail problem. Without a record of what changed and who changed it, the only information available is the current state, which is insufficient for understanding what happened or holding anyone accountable. Task version history solves this at the tool level. Every change is recorded automatically, without requiring anyone to document it manually.
"Task version history converts this from an unsolvable mystery into a 30-second lookup."
What task version history tracks
Every task in Melororium maintains a version history that records all changes:
- Field that changed, deadline, assignee, status, title, description, priority, custom fields
- Value before, what the field contained before the change
- Value after, what the field contained after the change
- Who made the change, the team member who made the edit
- Timestamp, exact date and time of the change, in the viewer's local timezone
Real scenario: deadline moved without notice
A client report is due on September 28. On September 25, a PM opens the task and sees the deadline is now October 5. The status shows 'In Progress.' The assignee has not mentioned the change. Without version history: Slack message to the team, 20-minute investigation, no clear answer. With version history: open the task → History tab → see that on September 24 at 14:32, Marcus T. changed the deadline from September 28 to October 5. Direct conversation with Marcus takes 5 minutes to resolve, either the change was intentional and the client needs to be notified, or it was accidental and needs to be reverted.

How to use the History tab
Version history is accessed from within any task. Open the task → click the History tab in the right sidebar. The history panel displays all changes in reverse chronological order, most recent first. Each change entry shows the field, the before and after values, the team member, and the timestamp. Changes can be filtered by field type (deadlines only, status changes only, etc.) or by date range.
How long is history stored
Task version history is stored for the lifetime of the workspace, there is no automatic deletion. Archived projects retain their task history. Deleted tasks lose their history when permanently deleted. The full workspace backup (available in Settings → Backup & History) includes task version history in the JSON export, so the audit trail can be preserved even if individual tasks are later deleted.
Which plan includes task version history
